Subject: [PATCH v5 01/11] drm: exynos: dsi: Restore proper bridge chain order
Date: Fri, 16 Sep 2022 23:47:21 +0530 [thread overview]
Message-ID: <20220916181731.89764-2-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20220916181731.89764-1-jagan@amarulasolutions.com>
From: Marek Szyprowski <m.szyprowski@samsung.com>
Restore the proper bridge chain by finding the previous bridge
in the chain instead of passing NULL.
This establishes a proper bridge chain while attaching downstream
bridges.
v5:
* exclude the NULL replacement in exynos_dsi_host_attach
v4:
* none
v3:
* new patch
